IMPROVEMENT IN BILLlARD REGISTERS.

Specification forming part of Letters Patent NO- 179,866, dated July 18,1876; application filed June 3, 11576.

To all whom it may concern:

Be it known that I, J osEPH RIVOIRE, engineer, of Paris, France, haveinvented certain new and useful Improvements in Counters; and I herebydeclare that the following is a full and exact description thereof,reference being made to the three figures of the accompanying drawingand to the letters thereon marked.

M y invention relates to a mechanical arrangement, whereby. units ortens and higher decimal numbers can be registered on counters or dialsby a simple touch of the finger, each registration, whether of units orof tens, being rendered apparent to the eye and audible to the ear.

My new counter is applicable to mechanical, industrial, and commercialpurposes in genera], by giving to it such size or form best adapted foreach particular purpose. I will describe it as specially adapted formarking iiilliard-playing, in which case it is destined to be tixed tothe band or border of the billiard-table by means of one or more screwsor otherwise, and is made as shallow as possible with rounded exterioredges, so as not to interfere with or inconvenience the action of theplayers.

In the accompanying drawing, Figure 1 is a plan of the front of mycount-er; Fig. 2, a plan of the back thereof, the closing-plate beingremoved, and Fig. '3, a lateral elevation through the line A A, Fig. 2.

In these figures, a, represents the case of the counter, and consists ina hollow metallic plate with rounded edges, preferably stamped out ofsheetiron, and b a back attached to a by means of screws 0 c in thegudgeons d d, fixed to the inner face of the case a. The mechanism ofthe counter is placed within this case, and consists in two similarseries of parts, the one having reference to the registration of units,and the other to that of tens, and the description of one will apply toboth; therefore, referring to the mechanism of the units, 6 represents awheel hung on the gudgeon d, and connected with a dial,f, also hung on d(and on the face of which dial are marked in their order the ten numbers0 to 9) by a pin, g, so that these two parts must forcibly tions by aclick, 2', pressed upon by a spring,

70. For the purpose of rotating this Wheel with its dial by fractions, 1make use of a second click, Z, pressed upon by a spring, 112,, and

pivoted at l in an arm, n, pivoted at n in the case a. A downward motionis imparted to this click I by pressure on an external stop, 0, jointedat 0 in the arm n, a spring, p, riveted to the inner edge of the case a,serving to bring the said arm back to its normal position on the stopbeing relieved of pressure, the depression of the click I being limitedby contact with the hub q of a sounding-spring, 1', which isacted on. byan inclined plane or bevel, 8 attached to the arm a at each deression soas to admit an audible sound. .1 a

For this purpose, on the arm beingdepressed, the edge of the inclinedplane passes over the spring a", and gradually depresses the same untiljust before the bottom of the click 5 strikes the stop q, at whichmomentthe entire inclined plane having passed over the spring, thislatter rises suddenly through the notch t to its previous position,emitting an audible sound.

Action of the counter: Supposing that both the zeros are apparent in theopenings 8 8 if the player wishes to register one point he sim-' plypresses down the stop 0 and releases it, thereby the wheel 6 and thedial f are rotated one-tenth, and the figure 1 made apparent at theopening 8 of the units. The click c', having allowed the wheel to makethe said fraction of rotation, re-enters the next cut. A succession ofsuch units can thus be registered until the zero once more is madeapparent. At this last fraction of rotation a projecting tooth, t,enters a nick in the wheel 0, indicating the tens and rotating the sameone-tenth, renders the figure 1 apparent at the opening 8 which, withthe zero at the opening of the units, makes up the figure 10. Thecounter can thus be made to register up to 99.

If the figures to be registered exceed9, then for greater rapidity thewheel and dial of the PATENT OFFICE tens can be rotated directly byoperating on the stop 0 after having released the same by disengagingthe hook at, as shown in the Fig. 3.

I claim as my invention- 1. A registering or counting device containedwi him a flat case composed of two parts, a b, one lodging within theother, as shown and described,the whole being adapted to be applied tothe border of a billiard-table, and to lie flush therewith, or toproject so slightly above it as not to interfere with or incommode theplayer.

2. The combination, with the wheels e, pro- JOSEPH RIVOIRE. Witnesses:
